Wikipedia[1] both corroborates and disagrees;
> A RISC is a computer with a small, highly optimized set of instructions
but later:
> The term "reduced" in that phrase was intended to describe the fact that the amount of work any single instruction accomplishes is reduced—at most a single data memory cycle—compared to the "complex instructions" of CISC CPUs that may require dozens of data memory cycles in order to execute a single instruction

- magicalhippo 6y agoFrom this[1] piece it seems the the original goal was indeed both: > Cocke and his team reduced the size of the instruction set, eliminating certain instructions that were seldom used. "We knew we wanted a computer with a simple architecture and a set of simple instructions that could be executed in a single machine cycle—making the resulting machine significantly more efficient than possible with other, more complex computer designs," recalled Cocke in 1987.
